Specification forming part of Letters Patent No. ll, dated January 12, 1875;

I December 21, 1874. l

To all whom it may concern: l Be it known that I, ANnREw FUL'roN, of Albany, `in the county of Albany and State of New`York, have invented certain new and ,useful improvements in Gas-Burners; and I ldoherebyy decla-re that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to which itpertains to make and use the same, reference being hadto the accompanying drawings and to the letters of reference marked thereon, which form a part of` this speciiieation.

"Figurel in thedrawing represents a vertical section of my improved gas-burner. Fig.

` 2 represents a detached vertical section of the main body of the burner; 3, a sectional view of the float and valve; Fig. 4:, the top or Y'. 'cap 4:torniertwith the diaphragm" and' valve;

f scat; Fig. 5, a sectional `view'oi' the burnerutip.

Similar letters of reference indicate corresponding parts.

This invention has relation to that class of gas-burners in which is used al rloat-valve; and my invention consists ,in the construction,

and combination of the several parts,` whereby a simple, cheap, and eii'ective burner is produced, as will be hereinafter more fully set forth. l

A in the drawing represents the base or main body of my burner, formed at its lower end w'ith an annular chamber, a, by the upward extension of the screw-nipple b and outer wall, c, the upper rim of said wall being provided with suitable screw-threads for the attachment ofthe cap B. This nipple b has screw-. threads, and is provided with a projecting rim or shoulder, dann its upper end, so that :when the burner is screwed upon the end of i the gasLpipe thejface of the latter will press np against said shoulder or rim, and make a perfect and tight-iitting joint, preventing' the escape of gas between the screw-threads of the pipe and nipple.

Within the base or main body A of the 1ourner is a cylindrical float, C. This float C han a convex top, f, forming a space suriciently large for the gas as it passes from the pipe-into the burner, assuring' the more perfeet pperation of'the float and valve. The. convex topf is provided witlroutletopenings application filed g g for the escape of the gas, and a long conical valve, h, which works in a conical valveseat in the diaphragm i of the hollow cap B, the valve being of suilicient length to guide of gas. A burner-tip, D,.is inserted inthe top of the hollow cap B.

The operation oi'.y my gas-burner is as follows: After the necessary quantity of glycerine or other suitable iluid is placed within the annular chamber a, the iloat (l is then inserted, the glycerine forming a tight joint be tween the nipple b and float O, preventing the escape of gas. The cap B is now secured to burner is ready to be attached to the gas-pipe. As `the gas passes from the pipe into` the chamber, between the nipple and oatit finds an outlet through the openings g g in the; convex top f of the oat C, filling the chambers equally upon either side of the float, and preventing the displacement of the glycerine and escape of gas. From the outer chamber, formed by the wall c and oat C, the gas passes into the hollow cap B through the valve opening in the diaphragm i to the 'burner-tip D. s

1f, at any time, the pressure of gas should become too great, the pressure against the convex top of the float C will cause the saine to be raised sufficiently to partially close the opening in the diaphragm i'. by the valve h, and thus making the supply of gas uniform.

Having new described nl v invention, what I claim, and desire to secure by Letters Patent, isy The body or base A, with an annlar/chamber, a, for the reception of glycerine or other' suitable fluid, and larr upwardly -projecting screw-nipple, b, formed with an annular riln iVitnesses: l
